In one session GPT-6.1 Sol found the impact of non-displayed trades on an exchange, 'an unobvious result that our research team did not initially consider'","Co-founder Jeffrey Yan: GPT-6.1 Sol is 'currently our most-used model given its token efficiency'; GPT-6 Astra gave the largest speedup on an internal latency benchmark; GPT-5.6 Terra used for targeted security checks; GPT-6 Luna in testing","Security: Daybreak used to have agents penetration-test the simulation environment for breakouts to the wider network before launches","The openai.com page returned 403 to direct fetches; read via a text-extraction proxy (r.jina.ai)"],"key_numbers":[],"tags":["agents","codex","long-horizon","quantitative-finance","gpt-6-astra","gpt-6-1-sol","daybreak"],"science":null,"body_md":"## What happened\n\nOpenAI published a customer story on Third Moment Research, a startup building a \"self-improving AI system\" that studies agent\nbehaviour, finds recurring weaknesses and generates thousands of synthetic scenarios to train agents on them.
